GARAGE-DOOR CONTROL.

Specication of Letters Patent. pgttnted MUM?, 2i, 922

Application filed November 4, 1920. Serial No. 421,619.

trated in the accompanying drawing, in'

which: l

Figure 1 is a plan of av garage. Figure 2 is a sectional elevation.Figure 3 is an enlarged detail of a crosshead for operating the doorsalong the line 3 3 in Figure 2. Figure 4 is a side elevation ot 'Figure3 along the line 4-4 in Figure 1.

Similar numbers ot' reference refer to the same or ysimilar o partsthroughout the several views.

Referringin detail to the drawing, l have illustrated in outline thewalls 5, the floor 6, the ceiling 7, and the doors 8 of the usualgarage. To each of these doors I have hinged a connecting rod 9 by meansof theA bracketlO. The two rods 9 are joined together by means of a bolt10A which threads into a crosshead 11 which slides on the fixed shaft 12on which it is prevented from rotating by the pin 13 which moves freelyin a splineway in the shatt 12. The shaft12 is supported at either endin the brackets 14.

On the lower side ofthe crosshead 11 is hinged a connecting rod 15 bymeans of the shouldered screw 16 which is prevented from turning bymeans ot the cotter 17 passing through the crosshead 11.

The further end of the connecting rod .15 is attached to an adjustablecrank-arm 18 which is secured to a worm I wheel 19 mounted in the frame20 and driven by the worm 21 on the shaft 22, which is rotated by thegrooved pulley 23, which, iny turn, is driven through a round belt 24from` the pulley 25 on the motor 26.

Projecting laterally lfrom the crosshead 11 is an arm 27 whose enlargedend 28 is A tapped for the rods 29 and 30, both of which on the threadedportions ot the rods and jamming same against the member 284 when therods 29 and30 are properly adjusted. The downturned ends 31 act as tripsfor engaging the arm 32 of the toggle switch 33, one of the members 31throwing the switch in one direction and the other throwing'lt in theopposite direction. The switch 33 is placed in the motor circuit 34which isalso controlled by a switch-35, which is placed out on thedrivewayA at a point accessible from the drivers seat when the car isstopped sinhciently tar Jfrom the garage to permit the opening of thedoors.

It is evident that bythe use Aof a connection to the lighting circuitthat switch 35 may also vcontrol the light wvithin the garage, withoutdeparting from the spirit of my invention. ,Y

lVhile I am aware that other devices have been constructed for thispurpose employing reversible motors, etc., with their at? tendantcomplications, I -have chosen lto use theordinary crank motion as thesimplest form for my device, permitting thereby the` use of a one-waymotor, and providing a maximum leverage for the operating parts whenstarting to close or stoppin the mo tion ot the doors when closed. lysetting the tripping mechanism so that the door will close with thecrank arm 18 on a dead center it would be impossible to open the garagedoors regardless of the pitch of the worm 21.

Then desiring to use this device on garages having double doors it i'sonly necessary to place an evener across the two crossheads 11 andattaching thisevener to the connecting rod 15, all of which could bedone without departing from the spirit of my invention.

The operationof my device is`as follows:

' Then desiring to enter the garage it is only necessary to operate theswitch 35, which -is a three-way switch wired as indicated.

the c'rosshead 11 toward the front of the garage, thereby forcing thedoors 8 outwardly until a point is reached where the member'31 engagesthe4 lever' 32 and automatically stops the motor.

It will be observed that the toggle switch is necessarily a three-wayswitch in order' that the motor can again be started after it has beenstopped by means of the trips 3 1'. The operation of the switch 35 willthen continue the rotation ot' the motor and the` completion of theCycle by the crank arm lS-whieh will restore the doors S to their formerclosed position.

ll'hile I have thus illustrated and deleeribed my invention it. is notmy desire to limit myself to this` precise. form o r method ofapplication. but intend that it shall cover all forms and modificationsthat fall fairly Within the appemled claims.

' What l claim as new and desire to protect by Lettere'latent of thellnited States is:

l. A garage door consisting.r of a pair of swinginga doors. incombination with a fixed horizontal rod mounted at right angles to themeeting point ot' the doors near their top, a crosshead on Said rod, twoconnectiuprods branching` out from said crosshead and attached to theswinging ends of the doors, a one-Ava)v motor, a crank driven h v saldmotor whose axle is at right angles to and in the same vertical planewith said" fixed rod, a connecting rod joining said crank to saidcrosshead, adjustable pendant stops on said erosshead, a three-Waytoggle switch whose lever is moved between said stops, and a three-Waybutton switch Wired with said toggle switch toveontrol said n10- torfrom sai .l crossl1ead or by hand.

In a door closing device7 the combination of a motor driven dooractuating mechanism havingj'a. erosshead member provided with a lateralprojecting standard through which are threaded from oposite sides a pairof down-turned. trip members, and a fixed toggle switch in the circuitof said motor having its operatinzg` lever between said do\vn-turnedtrip members.
